Reminds me of the thread about electric-powered forced induction a
while back. I think it was Dennis Jensen who worked out that in order
to get the electric blower to operate at a level that would create any
kind of improvement at all (so small you probably wouldn't even feel
it with your butt-o-meter), it would take 5 alternators. We can drive
those 5 alternators using fairy wishes, but most people will have to
resort to using the engine to drive them.

Done and dusted, and not by Nissan and not perpetual motion :-)

And of course, some of the gravitational potential energy stored in the car at the top of a hill is used to actually get
the car down the hill :-)

Not efficient enough I wouldnt think, it would drain more than it could recharge to run the
alternator.

Why don't they lay a big slot car track with a gov-co robot on the controller,
then if you get flung off on a corner or caught speeding it's gov-co's fault?
